A/C help, hole in core support - The 1947 - Present Chevrolet & GMC Truck Message Board Network

walker · 05-12-2004, 08:03 PM

I need to add a hole in my core support for my A/C lines to go to the condensor. I replaced the core support with a non A/C one when my truck was wrecked, and I forgot to measure the hole size and where it goes. If anybody can give me a quick measurement I'd appreciate it, as I am trying to get the a/c back together before it gets too hot here. Opps, too late it is already hot, maybe I'll get it before it gets scorching. BTW, it is a '67 C-10 with a 350, original style frigidaire compressor(mounted on the P/S valve cover. I have the A/C Battery box and all other components, just need the hole.
Thanks, Andy

Here are two pics, both factory 72's. The first pic is without the grommet in the hole. The hole size is 1 7/16".

The second pic is with the grommet, (both lines go through the same hole).

The center of the hole is 3 1/2" from the edge of the verticle reenforcement.

Hopefully there is a dimple.

I saw the dimples, I wasn't sure if that was what it was for or not. Thanks, You guys are the greatest, gals too!

I bought a hole punch at the used tools store. Makes a real pretty hole. Just line it up with the dimples as other have pointed out.
